ELEo'rnIo swrrorr. v

To all whom it may concern:

Be it-known that we, EDWIN States, and residents of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Elecspecification. v This invention has for Its ob ect an electric switch which is particularly simple 1n construction, and highly efficient and durable in use, and especially in which'the parts are compactly arranged. The IH VFDtIOI). consists in the novel features and 1n the combinations and constructions hereinafter set forth and'claimed.

bodying my invention. V s

. F'gure2 is a side elevat onthereof.

Figures 3 and 4 are respectively, elevations looking to the rightrespectively in Fig. 2.

Figure 5 is asectional view on line 5-5,- Fig. 4. v

This switch comprises generally, a base, a support mounted on the base, a.sw1tch arm mounted on the support and pivoted thereto, an operating leveralso pivoted to the support and having an arm extendin fails to act.

crosswlse of the axis of the switch arm an movable in an are from. either side thereof to the other, and a spring connec'tion between the arm of the lever and'the switch arm arranged to throw the switch when the lever has been operated to tension the spring and shift it to the opposite side of the ax s of the spring arm to thaton which it is located when the movement'of the'operating lever begins. v

The invention further consists in means,

throw the sw tch arm or give a start ng.1m-

between the lever and the switch arm to positively shift the same in case the spring 1 designates the basewhich may be'of any suitable form, size and construction, here shown as a block of insulating material. v

2 is a support here illustrated-as includin two uprights arranged parallel to each other, this. support being preferably U- shaped in general outline and having its "A; OilLIl-Y and FLOYD C. SMITH, citizens of the United branches forming the uprights and its intermediate portion secured'to the base as by screws 3 extending through the base J from the rear side thereof through the interme .diate part of the support. I i 4 is the switch arm which is ,U-shaped in general outline and has its'branches 5 extending on opposite sides of the u rights 2 and mounted on the. pivots'or stu s6 supported b the uprights. i

7 is t e operating lever here shown as angular in form and pivoted at 8 .to the uprights at one side of and parallel to the axis '6 of the switch arm 4, the lever 7 having an arm 9lex'tending horizontally crosswise of the axis of the pivot 6 of the switch arm and normally arranged on one side of such axis as below the same as shown in Fig. 5

and movable to the other side or above the axis when the switch arm is moved into the position shown in Fig. 2; During the move-- ment of the switch arm across theaxis 6, a

spring is tensioned and in turn throws the switch arm.

10 designates the spring which pression. spring coiled about a guide rod. 11 suitably plvoted at 12 to the end of the ,arm 9 of the lever 7 and slidable in an Opening '13 formed in the intermediate part of the switch arm, the spring abutting against the inner face" of the intermediatepart'of. the

switch arm and a shoulder 14 on the inner end of the guide rod 11 near the end ofthe lever arm 9. 1 The switch arm or the branches thereof are also formed with spaced apart shoulders or 'inturned lugs 15, 16 on the oppositeside is a com of theaxis 6. to that on which theinterme;

diate part of the switch arm is located and. the arm 9 of the lever 7 is formed with l alterally extending shoulders 17 movable between the shoulders or lugs 15,116 in order to"'engage oneof the same when the lever 7 is moved in one direction orthe otherjan'd not act. The lugs or shoulders 15,16, form Y washers 24, 25 of insulation mounted on the! sleeve on opposite sides of the contacts. The

contacts are thus insulated from the branches 7 of the switch arm.

Barrier plates 26 of insulation are also 2 carried by the branches 5 of the switch arm the, support on an axis at one side of and.

and interposed between the contacts and be ing of sufficient radius to lap the inner sides of the terminals and prevent arcing across thecontacts 1818, or 1919 or the terminals 2020, or 21--21 through the metal portions of the switch construction.

This switch construction is adapted to mounted in a conduit box having anoperating handle movable through the box and engaging the lever In operation, during movement of the lever 7 to the right from the position shown in Fig. 5, the arm 9-moves about the axis 6 and in so doing compresses the springlO until the end or the pivot 12- of the rod 11 passes above the pivot 6. whereupon the switch arm is thrown by the spring into the position shown in Fig. 2. ,Upon movement of the lever to the left from the position shown in- Fig. 2 the reverse of this operation takes place. 1

Owing to the relative arrangement of the axes of the switch arm and the lever handle a particularly compact switch construction is provided.

What we claimis:

1. In a switch, a base, a support rising from the base, a switch arm pivoted tothe support, and an operating'lever pivoted to parallel to the axis of the switch arm, the operating lever having an arm extending crosswise of the axis of the switch armand movable across such axis, a compression spring interposed between the arm of the lever and the switch arm to throw the switch, the switch arm being also 'formed with spaced apart. shoulders and the arm of the lever being also formed. with a shoulspring fails to act, substantially as and for the purpose set forth.

2. In a switch, the combination of a base, a support mounted on the base, a switch an operating lever pivoted to the-support, and

connections between the operating lever and the switch arm, switch contacts carried by the switch arm, a barriercarried by and movable with the switch arm and arranged on the inner side of the contacts to prevent a arcing across the contacts and terminals on be the base withwhich the contacts coact, the barriers lapping the sides of. the terminals,

substantially as and for the purpose speci- 3. In aswitch, the combination of a base, a support mounted on the base including opposing uprights, a switch arm U-shaped in general form and having the branches thereof extending on the outer sides of the uprights and pivoted thereto, an operating lever pivoted to the support between the uprights and having an arm thereof extending crosswise of the axis of the switch arm and connections between the operating lever and the intermediate portion of the switch arm, pairs of switch contacts carried byand movable with the switch arm, pairs of terminals on the base withv which the contacts comb and barriers carried by the branches of the switch arm and arranged between the conas and for the purpose described in testimony whereof, we have hereunto signed our names at Syracuse, in the county of Onondaga, and State or" New York, this 29th day of September, 1920.
